[driverloader] Broadcom 4301 on Mandrake 10.0RC1 [eid-20040301-f99]

[freon]

Hello,

I now have DriverLoader working OK with Broadcom 4301 on Mandrake 
10.0RC1, except that WEP is not working. I tried the command
iwconfig eth0 key [key #]
with various permutations, such as including "open" or "restricted", and 
entering the key as a string, as 1234-5678-90ab-cd, or as 
12:34:56:78:90:ab:cd. Each time it returns the error,
"Error for wireless request "Set Encode" (8B2A): SET failed on device 
eth0; Operation not supported."
Is WEP operational? If so, how can I enable it?
